<p>A control-type combustion synthesis apparatus (10) comprises an ignition mechanism (12), a pressure sensor (14) for detecting the pressure within the apparatus, a nitrogen supply mechanism (15) for supplying nitrogen from the outside of the apparatus, a gas pressure control valve (16) having a nitrogen supply function and an in-apparatus reactant gas discharge function, means (23) for detecting the internal temperature of a reaction vessel (20), a first cooling mechanism utilizing a water cooling jacket (18), and a second cooling mechanism utilizing a cooling plate (22). The apparatus further comprises a temperature control mechanism which regulates the amount of cooling water supplied to the first and/or second cooling mechanisms according to the temperature detected by the temperature detection means (23) to regulate the internal temperature of the reaction vessel. A silicon alloy comprising, in terms of % by weight, silicon: 30 to 70, nitrogen: 10 to 45, aluminum: 1 to 40, and oxygen: 1 to 40 can be synthesized by combustion synthesis while regulating the internal pressure of the apparatus and the internal temperature of the reaction vessel to respective predetermined values. The above constitution can realize the utilization of silicon, which is an inexpensive metal, as astructural material for industrial use at low cost.</p> |
